Audio: The film's DTS-HD Master Audio 5.1 soundtrack is very good; it never overpowers the dialogue, nor interferes with it. You can understand each actor’s lines, and can distinguish each of them.
Percy Jackson & the Olympians: The Lightning Thief comes with a number of extras; however with the exception of the deleted scenes, they all clock in at less than six minutes.
There are deleted scenes which include an alternate introduction to Annabeth, more fighting, more running, and scenes trimmed for time. All nice to see, but they don’t really add much to the plot.
“The Book Comes to Life” features an interview with the author of the franchise, Rick Riordan. The author discusses what inspired him to write the series, what it’s like to see his characters come to life for the film, the influence of Greek mythology on pop culture today and how the series took some time to become a success.
“Inside Camp Half-Blood” this featurette covers the stunt and sword training the cast had to undergo for the film. It also pays attention to the design of the camp itself.
“On Set with Brandon T. Jackson” follows the actor portraying Grover as he spends time on the set. This extra also covers how Jackson’s legs were digitally removed to give him the animal legs as seen in the film.
“Meet the Demigods” spotlights the cast who briefly talk about their characters, the plot and more.
"Composing for the Gods: A Conversation with Christophe Beck" talks with film composer Christophe Beck who discusses how he scored the film.
So while Percy Jackson & the Olympians: The Lightning Thief is being compared to Harry Potter or called a Greek version of Harry Potter, it’s still it’s own entity and provides fun entertainment for the family. There’s been no word if there will be a sequel, but hopefully there will be and provide the opportunity to show that it can stand on its own two feet.
